Solid content and solid-liquid ratio?

This post was last edited by zfy_80522 on 2010-4-19 09:42. What is the difference between fixed content and solid-liquid ratio?
The solid content refers to the proportion of solids in the mixture, while the liquid-solid ratio represents the proportion of liquid to solids in the mixture; the values obtained from these two measurements should be convertible into one another.
As I understand it, the solid content refers to the proportion of insoluble substances in the final product, while the liquid-solid ratio usually denotes the ratio of the amount of liquid to the amount of solid that needs to be added during the production process. That is, the difference in terms used during the production process and the subsequent inspection process.
Is it a volume ratio, or a mass ratio? ? ?
It seems no one knows! ! !
1. Solid content: refers to the amount of solids contained in the additive or slurry. Method for determining solid content: Weigh approximately 2 grams of the sample accurately using an analytical balance and place it in a watch glass. It is then placed in an oven and dried at a temperature of 105°C–108°C for three hours. After that, it is taken out and weighed; it is then put back into the oven and treated under the same conditions for another 30 minutes, after which it is taken out again for weighing. This process is repeated twice. Compare the data from the three trials to determine whether a constant weight has been reached, and then calculate the solid content using the following formula. Solid content = Dry constant weight / Original weight of the material × 100%. 2. Liquid-solid ratio: The mass corresponding to a unit volume (usually water); it can also be understood as the density of a solution formed by adding a certain substance to water. It is often used to quickly determine concentration. The relationship between the liquid-solid ratio and the weight percentage concentration is as follows: Liquid-solid ratio = weight of liquid / weight of solid = (100 – concentration) / concentration. The weight percentage concentration is equal to the reciprocal of the liquid-solid ratio, multiplied by 100%.
